Abstract
Nitrogen N management is a key issue in livestockfree organic grain systems Relay intercropping with a legume cover crop can be a useful technique for improving N availability when two cash crops are grown successively We evaluated the benefits of four relay intercropped legumes Medicago lupulina Medicago sativa Trifolium pratense and Trifolium repens on N dynamics and their contribution to the associated and subsequent cash crops in six fields of organic farms located in SouthEast France None of the relay intercropped legumes affected the N uptake of the associated winter wheat but all significantly increased the N uptake of the succeeding spring crop either maize or spring wheat The improvement of the N nutrition of the subsequent maize crop induced a 30 increase in grain yield All relay intercropped legumes enriched the soil–plant system in N through symbiotic fixation From 71 to 96 of the N contained in the shoots of the legumes in late autumn was derived from the atmosphere Ndfa and varied between 38 and 67 kg Ndfa ha−1 Even if the cover crop is expected to limit N leaching during wintertime the presence of relay intercropped legumes had no significant effect on N leaching during winter compared to the controlThis work was financed by the CORE Organic ERAnet with the research project AGTECOrg by the Agence Nationale de la Recherche France under the Systera Program ANR08STRA10 and the Region RhôneAlpes France with the research project CPER Bio The authors gratefully acknowledge the Jouffray Drillaud firm for providing legume seeds T Lhuillery M Guérin G Goulevant for technical support and C Holland for revising the text in English They also give special thanks to the organic farmers JM Brun JM Chancel P Robin P Vacher and D Valentin without whom this study would not have been possible
